Near the start of this abstract collaboration, Yoko Ono seems to cackle “mwah-ha-ha!” amid groans, chants, improvised poetry and impressionistic sex noises. Humor was part of the pioneering sound art she explored with John Lennon – alongside joy, fury, lust and glossolalia craziness. And so it is here. Recorded before Sonic Youth‘s Kim Gordon and Thurston Moore announced their separation, the voice-and-guitar cacophony might suggest avant-garde couples counseling. But what’s most remarkable is how legible it sounds. And maybe it should, since it distills the kind of audio radicalism these three have channeled into pop music for decades.
